UNITED STATES PATENT FFIGE IMPROVEMENT IN BRACKETS FOR HOLDING LAMPS.

Specification forming part of Letters Patent No. I 79,471, dated July 4,1876; application filed December 23, 1875.

To all whom it may concern Be it known that I, HENRY CAMPBELL, of SanFrancisco, in the county of San Francisco, State of California, haveinvented a certain new and useful Improvement in Brackets, of

which the following is a description sutficiently full, clear, and exactto enable any person skilled in the art or science to which my inventionappertains to make and use the same, reference being had to theaccompanying drawing, forming a part of this specification, in which-Figure 1 is an isometrical perspective view.

My invention relates principally to that class of brackets which aredesigned for holding lamps, flower-pots, &c.; and consists in a novelconstruction and arrangement of the parts, as hereinafter more fully setforth and claimed, by which a simpler, cheaper, and more efi'ectivedevice of this character is produced than is now in ordinary use.

The nature and operation of my invention will be readily obvious to allconversant with such matters from the following description.

In the drawing, A represents a table or shelf by which the bracket issupported 5 B, the body of the bracket, and F the arm. The lower portionof the body is U-shaped, forming a bow or clamp for grasping the edge ofthe table, and for that purpose is provided with the thumb-screw J, theupper portion being elongated to form the standard C. The arm F isarranged to swing freely in a horizontal direction by means of avertical pintle, 01, (only partially shown,) which is fitted to worknicely in a hole or socket in the upper end of the standard, and isrendered adjustable therein by means of the set-screw D. The outer orfree end of the arm is provided with two elastic clamps or holders, G H,arranged horizontally on the stud a. The ends of these clamps are curvedor bent upwardly, and are designed to grasp and hold the lamp orflowerpot carried by the arm, and for that purpose may be movedindependently of each other, as shown by the dotted lines, thus enablingthe lamp, or other article, to be easily introduced.

It will be obvious that my improvement is especially adapted for usewith sewing-machines, as well as in nearly any position where a portablelamp is required, being readily and easily attached to the side of atable or shelf, and adjustable both vertically and horizontally by meansof the screw D.

Having thus explained my invention, what I claim is 1. The improvedbracket described, consist ing of the body A, provided With the screwJ,standard C, and screw D, in combination with the arm Fprovided withpintle d, and clamps G H, constructed and arranged to operatesubstantially as set forth.

2. In a bracket, substantially such as described, the arm F providcdwith the elastic clamps G H, constructed and arranged to operatesubstantially as set forth and specified.
